AppFlow : Managing Flow Reporting Statistics

NetFlow Activation and Deployment Information
SonicWALL recommends careful planning of NetFlow deployment with NetFlow services activated on strategically located edge/aggregation routers which capture the data required for planning, monitoring and accounting applications. Key deployment considerations include the following:
NetFlow is in general an ingress measurement technology which should be deployed on appropriate interfaces on edge/aggregation or WAN access routers to gain a comprehensive view of originating and terminating traffic to meet customer needs for accounting, monitoring or network planning data. The key mechanism for enhancing NetFlow data volume manageability is careful planning of NetFlow deployment. NetFlow can be deployed incrementally (that is, interface by interface) and strategically (that is, on well chosen routers) —instead of widespread deployment of NetFlow on every router in the network.
